Production of raw material from the North Westfjords / Production of raw material from the North Westfjords

About 10 thousand tons of raw materials are transported from the northern Westfjords for processing elsewhere. Most of that catch is exported ungutted, so it is not only filleting processing that loses raw materials, but also parties that produce products from by-products, such as head drying and liver producers. The idea of forcing a party to gutt and possibly head catches is therefore tempting. The conclusion of this project, however, is that this is very inefficient and the overall effect will be negative. First, the gutting coefficients in the Westfjords are such that fishing companies would lose quotas with a gutting obligation. Secondly, buyers in the south of the country, who process fresh fish for flight, are willing to pay an additional 20 ISK / kg for fish that reaches trucks that leave at 15:00 according to schedule. If fish are gutted after landing, it is impossible to bring them catch for this transport and that fish will wait for transport until the next day. Fish that goes directly for transport has arrived at a processing house in the southwest area at about 04:00 and has been gutted for processing starting at 07:00. The fish is then ready for flight, which in some cases leaves around Keflavík Stadium around noon. This is therefore an economical arrangement that maximizes value creation in the fisheries sector in Iceland.

About 10 thousand tons of whole round fish are trucked from northern Westfjords to fish processors in south / west region of Iceland. Most of the fish is exported un ‐ gutted and therefore it is not just the filleting factories missing raw materials, but also those producing side product like cod heads drying and liver canning. The concept idea of this project was to force vessels owners and fish markets to head and gut the fish before trucing and looked like a tempting idea. However, the outcome of this work is that this would be inefficient and the overall effect will be negative. Firstly, the gutting standard given by the Icelandic authority is 16% but the average radio in Westfjords is only 12%, so the vessel owners would lose the difference in quota. Secondly the customers in the south / west are willing to pay extra 20 kr / kg for fish reaching the scheduled truck leaving the area at 15:00. If the fish would be headed or / and gutted it would not be ready for trucking, and be leaving the day after. Fish going straight from vessel at the harbor for trucking will be delivered in a fish plant in the south west at around 04:00 following morning. It will be ready for filleting at 07:00 and can be exported by airfreight around noon. Here is an advantageous arrangement case that maximizes value for the fisheriesin Iceland.

Improved utilization of lumpfish

The Ministry of Fisheries and Agriculture's regulation, No. 1083/2010, made it obligatory to bring all grayling catch ashore after 2011. It was therefore necessary to react quickly and find a market for the grayling itself, but only the roe had been harvested and the rest thrown into the sea. . A great deal of entrepreneurship had taken place for several years, and it is worth mentioning the National Association of Small Boat Owners and the export company Triton in that context, which together built up a market for grayling in the Chinese market, with a bang and all. It should be noted that the roe is about 30% by the weight of the grayling, while the whale with the head and tail is about 55%, of which the fillets are only 14% of its total weight. There was a lot of work to be done and it is clear that there is great value in this underutilized fish species and great opportunities would be created in many coastal settlements for the production and export of grayling. At the same time, increased income for fishermen and the fishing industry, as well as the fact that the grayling was now mostly brought ashore, which created a lot of work for production parties. Cutting for the Chinese market is different from the traditional method and requires more complex procedures, but it requires better working conditions that do not exist on board small fishing boats. There was little information on the chemical and nutritional content of grayling, but such information is necessary when marketing products. A detailed report was prepared on the material and raw materials are used in many parts of the country. Shelf life tests were performed on frozen grayling. A conference was held in Patreksfjörður where stakeholders in the fishing, processing and export of grayling were invited to discuss the interests of the industry.

A new regulation from Minister of Fisheries and Agriculture, No. 1083/2010, require returning all lumpfish fished in Iceland, after 2011. A quick action had to be taken to find markets for lumpfish itself, but only the roes which have been processed but the rest of the fish have been discarded into the sea. With entrepreneurial activity for some years now new markets have been developed in China, by the National Association of Small Boat Owners in Iceland in cooperation with the export company Triton. It should be noted that the roes are only about 30% of the total weight of lumpfish, with head and tail about 70% of its total weight. There was much to be done to save value in the lumpfish business and great opportunities for small communities relying on this business and find a market for the lumpfish product and create extra value for stakeholders. Furthermore, increased income for fishermen and fishing communities by creating valuable work by processing the fish at shore. Gutting and trimming the lumpfish for the China market is different from the traditional approach and calls for more sophisticated self-administration, but it requires better working conditions that do not exist on board small fishing boats. Very little information on chemical composition and nutrient value has been available for lumpfish products. An in-depth report on this subject was prepared, using samples from different regions in Iceland. Self ‐ life experiments were prepared by this project. A work shop was held in Patreksfjordur in May 2013, with stakeholders from the lumpfish business participating.

Small vessels - Optimizing catch value

The catch of small boats has the potential to be the best raw material available, as it is hardly possible to think of a fresher fish than the catch of day-trippers fishing on line or hand gear. Improper handling can, however, have the effect that small-boat fish do not live up to the expectations placed on them, which in turn means that it is not possible to process the catch into the most valuable products. Often, however, relatively small changes in working methods are required to ensure that the catch is under the brand name as a fish of maximum quality. This report discusses the issues that most affect the quality and shelf life of small boat fish, measures and comparisons are made of various influencing factors, reports on the preparation of guidance and incentive material published in connection with the project, and finally proposals are made for improvements in the value chain of small boat fish. The main emphasis in the project was on the preparation and distribution of teaching and instructional material for seafarers. A booklet and leaflets were published and distributed to all small boat fishermen in the country, and it is expected that the result will be reflected in increased knowledge of the importance of good handling of fish. Interested parties can contact Matís and receive the brochure by post, but it is also available on the company's website, ie. www.matis.is/media/matis/utgafa/Mikilvaegi‐godrar‐medhondlunar‐a‐fiski.pdf

The catch of small day ‐ boats using handline or longline has the potentials of being the best available raw material for the production of high value seafood. Improper handling has however often resulted in poor quality of this catch, which makes the products unsuitable for high ‐ end markets. Generally speaking there is however only need for relatively small adjustments in handling procedures in order to allow fish from small day ‐ boats to live up to its potentials as top quality seafood. In this report are discussed various quality issues related to small day ‐ boats. Measurements and comparisons are made between quality factors. Work related to writing, publishing and distribution of an educational brochure and other quality inducing material is accounted for. And finally there are brought forth suggestions on how to improve the value chain of catch from small day‐ boats. The main focus of this project was awarded to publishing practical and easy to understand educational material for fishermen. A brochure and a one ‐ pager were published and distributed to every small vessel in the Icelandic fleet. Hopefully, this educational material will be widely used amongst fishermen and contribute to improved knowledge on the importance of proper handling of seafood. The brochure is available at Matís and online at www.matis.is/media/matis/utgafa/Mikilvaegi‐godrar‐medhondlunar‐a‐fiski.pdf

Processing in line boats / Processing in line boats

This project is a collaborative project of the following companies; Matís, Brim, Samherji, Vísir and 3X Technology. The aim of the project is to improve the processing processes of longline vessels with a view to reducing the cost of processing, increasing work efficiency and product quality. The project includes the results of a voyage with the icefish trawler Stefni ÍS, where the goal was to perform different refrigeration and bleeding experiments on cod and thus find out what is the best processing method / processing treatment with regard to the quality of the product. The processing deck on longliners will be designed differently, but the same units are used to maximize the quality of the catch. Several groups were taken who received different processing treatments on board. The groups then went to the processing of Hraðfrystihús Gunnvarar where they underwent a sensory evaluation test in the color and release of the fillets. The main results of the project showed that bleeding in the sea, preferably with a lot of water change, before cooling, gives a better color - the meat quality of the wreck. There was no significant difference between the groups in terms of loss, as they all had similar results.

This project is a collaboration work between; Matis, Brim, Samherji, Vísir and 3X Technology. The object of this project is to improve the process in line boats, by reducing production costs, improve working conditions and product quality. This project includes payoff from voyage with the ice-fresh trawler Stefnir ÍS, where the objective was to carry out difference bleeding and cooling methods on cod and find out which methods is efficient regards to the quality of the product. The processing deck in line boats will be implement difference, but same unitary will be used to increase the quality of the catch. The primary conclusion from the research on board Stefnir, is that bleeding in sea before cooling the fish, gives better results regard to the color of the fillet. The research also shows that there was not a significant difference between groups regards to results in looseness of the fillet.
